LAM P-BURNER.

SPECIFICATION formingpart of Letters Patent No. 728,166, dated May 12,1903.

Application filed July 25, 1902. $e1ial No. 117,016. (N0 model.)

To all whom it may concern.

Be it known that I, GEORGE A. HALL, a citizen Of the United States,residing at Buifalo,

in the county of Erie and State of New York,

have invented certain new and useful Improvements in Lamp-Burners, ofwhich'the following is a specification.

This invention relates to that class of lampburners which are providedwith chimneyholding arms adapted to impinge against the Other objectsare to provide a simple, efficient, and reliable'burner in which thechimney-holding arms are simultaneously operated bya movable annulus,which latter when moved in one direction will cause the chim ney-holdingarms to be locked in their impinging position against all jarring andshaking of the lamp and will be held in such-locked position until bythe exertion of sufficient force the said annulus is moved in theopposite direction.

To this end my invention consists of a burner having a number ofvertical rock-arms with curved impinging upper ends and cranks at theirlower ends, an annulus having radial slots with which the crank ends ofthe said rock-arms engage and which is; arranged to turn back and forthon thebu'rner-body. It also consists in the new and novel arrangementand construction of parts, as will be hereinafter described, and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a central vertical section of a burnerembodying my invention and used in connection with a lampchimney. Fig. 2is a side elevation of my improved burner, showing the chimney-holdin garms rocked to engage the'inner side ot'a' lamp-chimney. Fig. 3 is asimilar view showing the chimney-holding arms rocked to permit thelamp-chimney to be secured to or removed from the burner. Fig. 4 is aplan view of the burner, showing the chimney-holding arms in theposition they assume when impinging againsta lamp-chimney. Fig. 5 is aninvertedview of'ihe burner.

;S .iinilar1numerals of reference indicate cor- 1i respondingpartsin theseveral figures.

The numeral 1 designates the lamp-burner -takenas-a=whole, and 2 thelamp-chimney.

Thefburne'r-body 3 may be of any common construction having a rim orchimney-gallery 4, a wick-tube 5, wick-raising mechanism 6,

slotted cone 7, and screw-neck 8, which is screwed into theoil-reservoir of the lamp. Vertically-disposed chimney-holding arms 9are journaled to rock in the gallery? or other suitable part ofiheburner and at their upper ends are preferably curved outward andupward to conform to the shapeot the chimney. It is obvious thatif thechimney isof a shape diiferent fromfthatshown .in the drawings hereofthese arms will beishaped to conform thereto. Thelower ends of thechimneyrhol'dinga'rrns are .offset or bent into the form of cranks 10.To keep these chimney-holding arms in their proper'position, each isprovided with acollar 11, which bears against the upper end ofa'bearing-sleeve 12, secured to, but forming part of, the chimney.-gallery. Any other arrangement of journalin g the chimney-holdingarmsmay be resorted to without departingfroin my invention.

Held On thebody of, the burne'r so as to partly revolve backand forth isan'annulus 13, which may be Of.-any..'construction and which is providedwith. radial slots-14, with which the lower crank endsfo-fthechimneyholding arms engage. The disposition of the crank ends ofthe-said arms are so arranged with reference to the upper impinging endsthereof that the turning of the annulus 13 in one direction causesthe'cranks 10 to ride in the radial slots and simultaneously swing Onthe journals of the arms of which they form part, while the impingingupper ends are swung inwardly to clear the baseof the lampchimney, thuspermitting the latter to ,be removed with ease and without obstructionand when removed allowing the same to be seated against the gallery ofthe burner. On

ICO

turning the said annulus in the other direction the crank ends, by themedium of the radial slots in which they are held,are'again caused toride in said slots and simultaneously swing on the journals of the armsof which they form part, while the upper impinging ends of thechimney-holding arms are swung outwardly against the lamp-chimney andslightly beyond the dead-center to lock the arms against movement exceptby the turning of the annulus 13 in the reverse direction from that lastdescribed. As the impinging ends of the chimney-holding arms reach thedead-center the crank ends thereof have about reached the inner end ofthe radial slots 14, and the further movement of said crank ends is onlysufficient to permit the upper impinging ends to pass the deadcenter,where they are locked against further movement by the crank ends bearingagainst the inner ends of the slots.

Having thus described my invention, what I claim is 1. Alamp-burnerprovided with a number of vertical rock-arms, an annulus movable on theburner, and means for connecting said annulus with the verticalrock-arms to cause the latter to rock on moving said annulus.

2. Alamp-burner provided with a plurality of chimney-holding arms, oneof which at least is journaled to rock in the burner and has the lowerend bent to form a crank and all having their upper ends bent or curvedto form impinging offsets, an annulus held to the burner-body to partlyrevolve thereon and having a radial slot in which the crank end of saidrock-arm rides, said annulus causing the latter to rock in its bearingand force form impinging oifsets adapted to impinge against the innerside of a chimney, and having their lower ends bent to form cranks, anannulus arranged to turn on the burner and having radial slots in whichthe crank ends of the rock-arms ride, said annulus on being turned inone direction causing the impinging offsets to swing outward beyond thedeadcenter and the crank ends to move against one of the ends of theradial slots to check the further movement of the rock-arms, and onbeing swung in the other direction causing said impinging ends to swinginward to permit the lamp-chimney to be removed from or set onto theburner, substantially as set forth.

4. A lamp-burner provided with a plurality of vertically-disposedrock-arms having their upper ends bent or curved to form grippingoffsetsdesigned to engage a chimney on the inner side thereof and having theirlower ends offset to form cranks, and an annulus having radial slotswith which the crank ends of the said rock-arms engage, said annulusbeing adapted to cause the upper ends of said rockarms to impingeagainst the inner side of a lamp-chimney to securely hold the same tothe burner, substantially as set forth.

In testimony whereof I have affixed my signature in the presence of twosubscribing witnesses.
